The Wireless Presentation Timer is an innovative tool designed to enhance the management of presentations at events. It features a 7-inch touch screen wireless controller, enabling event organizers to control a 5-inch stopwatch on the podium remotely. This technology not only helps in keeping track of presentation schedules but also allows sending warning messages to speakers, ensuring presentations stay within their planned duration. The inclusion of red, yellow, and green warning indicators on the podium display aids speakers in timing their speech effectively, contributing to a more organized and professional event experience.
